Does quitting putty close the running command

Question

I was using rsync to copy 15GB files between servers using putty. I want to know that if i close putty terminal does that also termiates rync or not because file is not copied properly.

I have tried that when i am doing backups then even if i close putty then scrip continue to run in background

Answer 1

Assuming your goal is to have the rsync command continue to run, the simplest thing is to orphan the job. There are two ways to do this:

(rsync foo bar &)

The above will create the job detached from your terminal in the beginning, so closing the terminal will not stop it.

rsync foo bar & # or without &, then Ctrl-Z to stop, then "bg" to background
disown

The above will disown a running job, so you can close the terminal without stopping it.

Finally, you could use the program screen(1) or similar to keep a terminal session alive and intact (and able to be resumed) even when you end your Putty session.

Answer 2

Generally most command will quit if the console is closed. If you want them to keep running look at the NOHUP command (Nohup is No Hang Up Process, a hang over from the days of modems and 'hanging up' the phone)
